Calculate load factor in Gs from bank angle and see how maneuvering flight can affect stall speed. This free aviation calculator helps pilots better understand turns, G loading, and training concepts.
Enter bank angle to estimate load factor in a level coordinated turn. The calculator also shows the related stall speed multiplier.
This calculator assumes a level coordinated turn. It is intended as a training and planning aid.
Load factor is the ratio of total aerodynamic load supported by the wings to the aircraft’s actual weight. In straight and level unaccelerated flight, load factor is 1 G. In a level banked turn, load factor increases because the wings must produce more lift to keep the aircraft from descending.
As bank angle increases, load factor rises rapidly. That is why steep turns require more lift and why stall speed increases during maneuvering flight.
| Bank Angle | Approx. Load Factor | Stall Speed Multiplier |
|---|---|---|
| 15° | 1.04 G | 1.02× |
| 30° | 1.15 G | 1.07× |
| 45° | 1.41 G | 1.19× |
| 60° | 2.00 G | 1.41× |
| 75° | 3.86 G | 1.97× |
Yes. Stall speed increases with the square root of the load factor. Higher G loading means the wing must generate more lift, which raises the speed at which it stalls.
No. Load factor can also increase during pull-ups, turbulence, abrupt maneuvering, and other accelerated flight conditions. This calculator focuses on level coordinated turns.
In a level coordinated turn at 60° of bank, load factor is about 2 G. That means the wings are supporting about twice the aircraft’s weight.
No. This calculator is a training aid. Always use approved aircraft limitations, POH or AFM data, and proper operational judgment.
